I've got the Sacrifice Altar project. One of the reqs is "Destroy Village X" (incidentally that village is right next door, right across some flat land). Is there any other way of destroying that village besides making my village greedy and hoping they'll pick that for attacking?

They are all progressing very well and I have a University, Customs House, Harbor and a Mill.
But from this point on they don't have have any projects (For the last 30-50 minutes no sign of any project) and I really need another ambassador for the Exotic, Toxic and Predator aspect.
